Patent GB-921543-A (GB)
Title: Process for permanently waving or straightening hair
IPC: A61K8/66
Filed: 1960-03-25
Abstract: Hair is permanently waved or straightened by treating it with a urea-containing aqueous solution or emulsion of a mercapto compound, e.g. ammonium thioglycolate, or an organic sulphur compound which can split up to give a mercapto compound, e.g. dithiodiglycolide, carbaminyl thioglycolic acid and ethyl xanthogen acetic acid, having a pH of 5-9 and adding urease or a urease-containing substance before, during or after placing the hair on curlers or curling the hair on cut-to-size strips of absorbent material, e.g. paper or cotton fabric, impregnated with urease preparation solution.  The hair may be wetted with water, wound on to curlers with the inter position of a urease-containing paper and then wetted with an acid thioglycolate solution to which shortly before use urea has been added or the hair may be wetted with the acid urea-containing thioglycolate solution and curled in the urease-containing paper. Alternatively the hair may be curled in the urease-containing paper and wetted with a urea-containing thioglycolate solution the pH of which has been adjusted to a little below 7.  When urease-impregnated absorbent material strips are not used the urease or urease-containing substance is preferably added to the urea-containing aqueous solution or emulsion of the mercapto compound shortly before its application to the hair.  The action of the waving compositions may be increased by increasing the temperature by use of a drier or vaporizer.  The urease-containing substance may be soya bean powder or jack bean powder or the extracts of these powders from which insoluble constituents have been removed.  In hair straightening processes the reagents are preferably applied to the hair in the form of a cream and straightening may be promoted by combing.  The compositions used may also contain wetting agents, perfume oils, buffering substances, e.g. ammonium dihydrogen phosphate and citric acid, and thickening agents.  Specifications 453,700, 689,641, 723,917, 735,303 and 780,037 are referred to.

Title: Process for the purification of gases for synthesis of ammonia
IPC: C01B3/02
Filed: 1930-04-04
Abstract: <PICT:0350120/III/1> In ammonia synthesis processes wherein the gases are recirculated the obstruction of the pipes by ammonium carbonate, formed by reaction between ammonia in the recirculated gas and traces of carbon dioxide remaining in the make-up gas, is prevented by mixing the make-up gas with ammonia in the presence of sufficient moisture to dissolve the ammonium carbonate formed.  In the illustrated apparatus the fresh gases pass through a purifier A and cooler B before reaching the synthesis chamber D and the effluent gas after removal of the greater part of the ammonia in E is recirculated to the point H.  A small amount of the recirculated gas is diverted through the pipe J and mixed with the make-up gas before the latter is dried in the cooler B.

[Also in Group XXX] Cigarettes issuing in rows from a cigarette-making machine are transferred in batches from a belt conveyer to a collecting box by a reciprocable sunction pick-up device. As shown, cigarettes S are fed from the delivery belt 9 of a cigarettemaking machine and arranged transversely in two parallel rows on a conveyer belt 1 which is disposed between sets of guides 13 by which collecting-boxes 14 are located for vertical movement. The boxes, which comprise a bottom, a rear wall and two end walls, are supported with their open sides towards the belt 1 by bars 15 interconnecting pairs of chains 16 which pass around sprockets 17, 18, the former being provided with adjustable friction brakes 33 and the latter being rotated intermittently through ratchets and pawls 19, 20 by links 21 coupled to a lever 22 which is coupled by a link 28 to a lever 26 on a shaft 27. A second lever 25 on the shaft 27 is coupled by a link 24 to a crank 23 and the upper ends of the two levers are connected by rods 36 to members 35 slidable on horizontal guides 34. A shaft 37, rotatable in the members 35, supports a suction head 38 formed with orifices 238 and carries a lever arm 41 provided with a roller 42 which engages a slot 43 in a member 44 which is periodically raised against the action of a spring 46 by a cam-operated arm 47. The head is thus given a combined reciprocating and rocking movement such that each orifice 238 is alternately positioned within one of the boxes 14 and over a row of cigarettes on the belt 1. The orifices are connected by pipes 39, 40 to a valve (not shown) which is so operated in synchronism with the movements of the head that the two orifices are alternately connected to a vacuum pump and to atmosphere when in their extreme positions. Thus, suction is applied to the left-hand orifice, Fig. 4 to pick up a layer of cigarettes from the left-hand row on the belt 1 at the same time as the right-hand orifice is connected to atmosphere to release the layer of cigarettes picked up from the right-hand row and allow them to fall into the right-hand box. The boxes are lowered by the chains 16 in steps equal in length to the diameter of the cigarettes so that the upper layer of cigarettes in each box is maintained at a constant level. When the boxes are full their bottoms engage discharge belts 29 which feed them on to guides 134, the lower transverse parts of the guides 13 at the delivery end of the machine being cut away to allow this movement.
